To all whom it may concern:

Be it known that we, Evsn'r M. HARRIS and CHARLES J. Ln VALLEY, citizens of the United States, residing at Sheiiield, in the county of Franklin and State of Iowa, have invented a new and useful Corn Harvester and Husker, of which the following is a specification.

Our object is, rst, to provide a machine for picking corn from stalks of two rows at a time in the field when it is propelled by horseshitched to an adjustable pole in rear of the machine. Second, to provide a carriage frame that is widest at its center, inclined inwards at its and specially adapted for supporting picking rollers in a forwardly and downwardly inclined position, an endless carrier between them and husking rollers in a rearwardly and downwardly inclined position as required to coact in gathering and husking corn as the machine is advanced. Third, to provide means for adjusting the pole andguiding the advance oi the machine and also for raisingl and lowering the front end of the machine relative to the ground. Fourth, to provide pairs of rollers for picking corn from stalks and locating one in each pair in a higher plane than the other as required to cause ears of corn to fall inwards upon an endless carrier to convey them upwards to fall upon husking rollers. Fifth, to combine three pairs of husking rollers to strip off husks and deliver the corn to a conveyer to carry it to a wagon at the side of the machine. Sixth,

to provide one roller in each pair of husking rollers with spiral grooves and the mating roller with a plurality of teeth for traversing the grooves and biting and tearing off husks. Seventh, to provide adjustable bearings for the outer picking roller in each pair to allow the roller to be self-adjusting relative to its mating roller and the corn stalks that enter between the rollers as the machine is advanced. Eighth, to locate endless chains above the picking rollers and provide them with fingers to engage corn stalks and .to coact with the picking rollers in gathering and delivering corn to the endless carrier between the two pairs of picking rollers. Ninth, to provide inclined platforms above the picking rollers to support the chains having fingers that project laterally relative to the platforms to engage corn stalks and ears. Tenth, to combine deflectors with the husking rollersvto direct corn relative to the rollers.

Our invention consists in the construction, arrangement and combination of elements and subcombinations as hereinafter set forth, pointed out in our claims and illustrated in the accompanying drawings in whichr- Figure 1 is a top view of the machine and shows the contour of. the frame and the positions of various operative parts relative to each other and the frame. Fig.

' 2 is a side elevation `of the machine from which parts of the pole are broken away and also shows the inclined positions ofv the picking rollers and the husking rollers relative to each other and the central uprights of the frame. Fig. 3 is an enlarged transverse sectional View and shows the positions of the two picking rollers at their lower ends relative to each other and the two parallel parts of the frame that supports them, the lower one in a fixed bearing and the upper one in a vertically adjustable bearing. Fig. ,4 is a horizontal sectional view of the vertical 'adjustable bearing that supports the upper rollerl in the pair. Fig. 5 is a rear view of the central upright position of the machine frame and the horizontal shafts and gearing connected therewith for actuating the various operating mechanisms in the machine. Fig. 6 is an enlarged sectional view that shows the gearing for transmitting ,power from one of thehorizontal shafts to the endless chains that have fingers for engaging and moving-corn relative to the picking rollers. Fig. 7 shows how th pole .is pivotally connected with the axle. Fig. 8 shows how the corn is directed from the picking rollers to the endless carrier by means of an inclined lplane between them. Fig. 9 shows how the deflectors n top of the husking rollers are supported between each pair of rollers a plane above the rollers as required tg direct corn to each pair of rollers. Fig. 10 shows how inclined planes are supported to direct corn to an endless carrier.

The numeral 10 designates an axle about seven and a half feet long, rotatablyconnected with wheels 12 about thirty t`wo inches in diameter, by means of ratchets 13 fixed on the axle and pawlsll pivoted to the wheel in such a manner that the axle will rotate when the machine is moved forwards and remain idle when the machine is .moved backwards. Bearings 15 are connected with the main frame and the axle 10 is rotatably mounted in the.bearings 15, as shown in Fig. 5, and project forward,'as shown in Fig. 2, to support a plurality of upright bars 16 fixed to the bearings to produce the vertical central part of the frame. The lower ends oi the uprights 16 are connected by a cross bar 17 and their top ends by a cross bar 18 as shown in 5. Horizontal angle bars 19 are fixed on the outside bearings 15 andtheir front end portions are inclined inward asshownin Fig. 1 and downward as shown .in Figs. land 2 and their rear portions extend in a straight horizontal plane and incline inwards as shown in Fig. 2 and their rear end portions extend in a straight horizontal plane and incline inwards as shown in Fig. 1. On the inside of the angle bars 19, at -some space therefrom, are bars 20 fixed to bearings 15 on the axle 10v as shown in Fig. 5 to extend forward and backward in parallel position with the angle bars 19 in pairs on. each side of the machine for supporting shoes 21 ixed to their front ends, as shown in Fig. 2, and gearing at their rearzends as shown in Figs. 1 and 2.

In the`top cross b ars 18 are fixed in pairs straight bars 22 and :connectedat their 'lower4 enklwith the fiori-'fi zontal bars 19 by square frames 23 fixed thereto, as shown in Fig.. 3, to. support the\lower=.ends'oipairs of; picking rollers 24. To the upper ends of the bars 22l are fixed square frames 25 to supporttheii-.i-ppervendsl; of the rollers 24 as shown in Fig. 8. The inner roller 24 ofeach pair is supported at its lower end in a bearing; 26 fixed to the frame 23 and the upper and outer roller 24 in each pair is journaled in anadjusta'ble bearing`27ithat is slidably connected with the inner upright of the m1-ten :traine :23 as- 'shown inl Figsand fin-a' plane"E abovethebearing"26.
